BARTON, OF BATTLE CREEK, MICHIGAN, AS SIGNOR TO AMERICAN STEAM PUMP COMPANY, OF.BATTLE CREEK, MICHIGAN, A CORPORATION OF MICHIGAN POWER ATTACHMENT FOR MOTOR VEHICLES Original No. 1,482,880, dated February 5, 1924, Serial No. 600,460, filed November 11, 1922. Application for reissue filed January 11, 1926. Serial No. 80,671.

This invention relates to improvements in power attachments for motor vehicles.

The main objects of this invention are:

First, to provide an improved power attachment for motor vehicles, which may be readily mounted upon a vehicle.

Second, to provide an improved power attachment for motor vehicles in which the parts are so arranged that the strain or pull of the driving belt is largely carried or sustained by the attachment, thereby avoiding the racking of the vehicle to which the attachment" is applied.

/ Third, to provide an improved power attachment for motor vehicles which enables a direct drive from the driving shaft of the motor.

Fourth, to provide an improved power attachment for vehicles in which the parts are formed and arranged so that they may be knocked down or disassembled for convenience in transportation and handling.

Objects pertaining'to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. T he invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Figure I is a front perspective view of my improved power attachment shown in operative position upon a motor vehicle of well known type, parts of the outline of the vehicle being indicated by dotted lines.

Fi re II is a detail view partly in vertical lon itudinal section, on a line corresponding to line 2-2 of Figures 1, V and VI.

Fi re III is a similar fragmentary see- I tiona view with the driving pulley supporting frame removed.

Figure IVis a fragmentary plan view par- Figure VI is a detail section on a line corresponding to line 6-6 of Figure II.

Figure VII is a detail section on a line corresponding to line 7-7 of Figures I and VI showing details of the frame and the manner of assembling and disassembling the same.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar reference characters refer to similar parts throughout the several views.

Referring to'the drawing, 1 represents a cross member of the chassis frame and 2 the front spring thereof. The engine body is represented at 3 (see Figure II) and the driving member or shaft at 4. In practice I remove the fan belt pulley with which the machine is usually equipped and substitute the fan belt pulley 5 having a forwardly projecting sleeve-like hub 6 terminating in the jaw clutch member 7. I also substitute a plate-like bracket 8 for a bracket usually employed to support the forward end of the cranking spindle, the cranking spindle being also removed; The bracket 8 has a flat face.

and an inwardly projecting arm-like portion which rests upon the frame member 1 and is clamped thereto by U-bolts as Illustrated, the bracket projecting upwardly above the frame member asshown in Figure V.

The bracket 8 is provided with holes 9 and 10 adapted to receive attaching bolts 11 of the pulley supporting frame 12 so that this pulley supporting frame is detachably secured to the bracket 8, it being intended that the bracket 8 shall remain in place and the supporting frame 12 being attached or removed as may be desired.

The frame 12 is provided with a bearing 13 for the spindle 14 of the driving pulley 15 This spindle or driven member is disposed longitudinally of the vehicle and in alignment with the driving shaft 4. The spindle of the driving connection between the driving and driven members. This shaft section 17 is provided with a clutch member 18 connecting with clutch member 7 and with a clutch member 19 coacting with the clutch member 16. This shaft 17 is a floating shaft; that is, it is mounted for axial movement being held yieldingly outward by the coiled spring 20 arranged in the hub or sleeve 6 to disen age the clutch member 7 and 18 and being held with all of the clutch members in engagement when the pulley supporting frame is mounted on the bracket as shown in Figure II.

The bracket 8 is provided with a conical .or outwardly tapered opening 21 while the clutch member 19 has a conical periphery adapted to engage this tapered opening when the frame 12 is removed, thereby preventing rattling of the parts.

I provide a pair of idler pulleys 22 which are carried by .the shaft 23 supported above and transversely to the driving pulley by means of the uprights 24 and the braces 25. .These uprights rest in seats 26 provided therefor in the arms 27 of the supporting frame 12, the arms being provided with plus 28 ada ted to en age holes 29 in the lower ends 0 the uprigIits, the uprights being engageable and disengageable with a tilting and swinging movement. This prevents the uprightsjarring off the arms. I

At the upper ends ofhe upri hts are bearings 30 for the shaft 23. The races 25 terminate in boxes 31 adapted to receive the ends of the shaft. The inner ends of the braces 25 are engaged with hooks or projections 25' on the chassis frame. The bearings 30 have forwardly projecting arms 32carrying the upright guide pulleys 33. The guide disk 34 is disposed between the pulleys with its tapered periphery projecting beyond the same. This guide disk is freely rotatable in either direction. r

The spindle of the pulley 15 is provided with a cross pin 35 with which a suitable crank may be engaged for cranking the engine should that be desired or necessary. The same crank is also designed to be engaged with the clutch member 19 when'the power mechanism is removed. The engine 3 is provided with a forwardly projecting hanger member 3 which is engaged with the supporting bracket 8, see Figures II and III,-so that the supporting bracket performs the double function of supporting the driven part and also of an engine hanger support. I

With this arrangement of parts the power mechanism may be quickly and easily applied to the motor vehicle or automobile and in operation there is little stress upon the parts. The belt 36 is supported and guided to very effectively deliver the power.

I have illustrated and described my invention in an embodiment which I have found very practical and as I have adapted the same for automobiles or pleasure vehicles,

I have not attempted to illustrate and describe my improvements with such modifications as might be necessary or desirable for attaching them to trucks and tractors as I believe the disclosures made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired. I
